Evaluation of the Resequencing Delay for Selective Repeat ARQ in TDD-Based Wireless Communication Systems

This correspondence deals with the modelling and analysis of the resequencing delay in Time Division Duplexing communication systems which adopt the Selective Repeat Automatic Repeat-reQuest error control strategy. Under the assumption that packet mis-ordering at the receiving end is induced by channel errors, the correspondence proposes an analytical approach based on the Absorbing Markov Chain theory in order to accurately predict the impact of the resequencing delay on the quality of the provided services. Numerical results, derived by means of computer simulations, are also given in order to validate the proposed analytical model.
